Flax seeds, which are very rich in fiber, are highly recommended because they positively influence digestion and aid transit.
In fact, like psyllium, flax seeds contain mucilage which swells and becomes viscous in the intestine. They are therefore excellent for promoting bowel movements.
They can be consumed daily, incorporated into many savory or sweet recipes. They can be added as ground seeds to yogurt, salads, soups, or even on meats with great flavor.
Like chia seeds, flax seeds have a reputation for having many health benefits in addition to a super effective laxative effect, however, they should be consumed in small quantities.
